TWIN FALLS, Idaho (AP) - The body of a woman found floating in the Snake River will be buried following fruitless attempts to determine her identity, authorities in south-central Idaho said.

The burial will be at 11 a.m. Tuesday at Sunset Memorial Park in Twin Falls, Twin Falls County Coroner Dennis Chambers told The Times-News (http://bit.ly/1nTlTR1 ). Chambers said he and his staff will attend.

A kayaker spotted the body Sept. 9 near Centennial Waterfront Park, and authorities said the body had likely been in the water an hour.

The 5-foot-7, 177-pound woman with hazel eyes was dressed in black, had no identification and lacked distinguishing features such as scars or tattoos. Her estimated age is 45 to 50.

Investigators say she likely jumped to her death from Perrine Bridge, but they have not ruled out other possibilities. Investigators have previously said it’s unusual that no vehicle or personal property was found nearby despite searches.

The woman’s fingerprints have been placed in national databases. Her DNA and dental information is also on file.

Twin Falls County commissioners recently approved a request to bury the body at county expense, which is about $1,250. Chambers said burying unidentified remains rather than cremating is an unofficial rule among coroners.

“You don’t know what the family’s request would be,” he said, noting burial also allows for exhumations later.

A Sunset Memorial Park spokeswoman said the woman’s grave will be the first with unidentified remains at the cemetery.
